IMPROVEMENT IN CU'L'I'IVA'I'ORS.

To all whom it may concern Be it known that I, JACOB H. B. KELLER, of Chambersburg, in the county of Franklin, and State of Pennsylvania, have invented a new-and llSeflll Improvement e that the folwhich will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which Figure 1 is a side sectional view of my invention.

Figure 2 isa plan or top view of the same.

Similar letters of refere nce indicate corresponding parts. I

This inventionrelates to a new and improved cultivator, and it consists in a novel construction of the same,as hereinafter fully shown and described, .whereby'the device may be used in rough or stony ground, without the liability of breaking orinjuripg it. In the accompanying sheet of drawings, A represents a rectangular frame, which is mounted on two wheels B B, and provided with a suitable draught-pole, 0.

Dis the drivers seat, placed on the rear part of the frame A, and E represents four shovel-beams, which.

are constructed each of two metal bars, a a, the front endsof the latter being secured by a rod, 1), in metal heads Ffwhich are attached to the front cross-bar, c,

of the fiame A. By this connection the beams E may be raised and lowered freely.

Between the rear parts of the bars, a a, 'of the beams E, standards, G, are'secured, by pivotbolts (1, one standard to each beam, and to the lower end of each stand: ard, a shovel, H, is attached, of any proper or desired form.

\ I represents India-rubber springs, which are placed in front of bearings, c, on the beams E, and J represents rods, which are secured to the standardsG, below the pivot-bolts d, and extend forward, and pass through the springs I. p

The springs I retain the standards G in a proper working-position, and in case any one of the shovels H meets with an obstruction, its standard, G, will yield or give, and said shovel allowed to clear itself and pass over a small obstruct-ion, while, in the'event of any one of the shovels coming in contact with a large ob truetion, the yielding of its standard will admit of the cam E being raised with facility, as the shovel will not become locked.

The beamsE have each an upright lever, K, attached, and these levers pass up through a cross-bar, e in frame A, and are within cbnvenient'reach of the driver, on seat D. By-means of these levers, the beams E may be raised individually, and all the beams and shovels may beraised simultaneously, by actuating a lever, L, which is within convenient reach of the driver, on seat D, said lever L being'attached to a hinged bar, e, on the frame A, to which bar the beams E are connected bychains'f.

From the above description, it will be seen that this device may be used on rough or stony ground, without the liability of being broken or injured, the shovelstandards are allowed to yield ,or' give and pass over small obstructions, and, in case of coming in contact with large obstructions, the standards, in yielding, admitof the shovels being readily raised, either singly, or. the whole of them, simultaneously, as may be reqnired.

Having thus described myinvention',

Lclaim as new, and desire to secure by Letters Pat- ,ent-

1. The pivoted standards G, arranged in connection with the rods J, 'Indianrnbber'springs I, and beams E, all arranged in the manner substantially as and for the purpose set forth.

2. The levers K, attached tothe beams E, and ar- 7 ranged in relation with the drivers seat D, substantially as and for the purpose specified.
